unset all variables

[asmith]

is that possible that i unset all the variables i have set up in a file  ?

 

i'm fetching some rows from mysql table :

 

while (aaa = mysql_fetch_array... )

 

then for each row i'm setting some variables like :

 

if aaa[name] = "john"
{
$a= true;
$b  = "name" 
}

 

 

now when the main while loop that is fetching  goes to the next row and in the next row aaa[name] wasn't "john"  , so $a shouldn't be true . so it skips the if part ... but as $a is set true from the last row, so although it skips the if part, but $a is still true .

 

as i 've set lots of variables , it takes so much time to search for them and fix them , wanted to know is that possible i reset all the variable AFTER each while loop results ?  ( if all the variables reset , then variabes in while loop ill destroy too )

 

 

thanks

<?php

$text = "bubbles";

echo $text;

unset($text);

echo $text;
?>

try

 

foreach ($GLOBALS as $strKey => $arrValue)
{
    if (!is_array($GLOBALS[$strKey]))
   {
         unset($GLOBALS[$strKey);
   }
}

$GLOBALS contain so many variables other than the variables i've set , cause no problem unsetting them too ?

[rajivgonsalves]

Yeah, thats the problem , either you unset everything or you have a list of your variables... in an array

[asmith]

ok  i guess i have to go down that road the highway !

[asmith]

hey rajiv ,

dosen't my variables have a specific location in $GLOBALS ???

can't we use that ?

[rajivgonsalves]

Yes they have but the location for anything you set will be at the current location I'll check and see if php has a function to distinguish between user variables and system variables.

thanks rajiv

yea just put them in an array like this:

 

<?php
$x = 0;
while($aaa = mysql_fetch_array...){
$array[$x] = $aaa['column_name'];
$x++;
}
// echo your variables....

unset($array);
?>
